Water stop structure of shield connector
In a water stop structure of a shield connector, a rear holder includes a main body disposed at a position facing the inner circumferential surface of the end portion of a shield shell in the connector extraction direction, and a protrusion formed to protrude from the main body along the electric wire in the connector extraction direction between the electric wire and the braided body. The braided body is disposed to cover the outer circumferential surface of the protrusion such that the end portion in the connector insertion direction reaches the connecting part. The tape is wrapped around the braided body in a spiral shape to cover at least the portion from the end portion of the rear holder in the connector extraction direction to the connecting part.
1. A water stop structure of a shield connector, comprising:
at least one electric wire to which a terminal is crimped at one end;
an electric wire holding member holding the electric wire in an inserted state;
a housing made of an insulating material, the housing holding the electric wire including the terminal on an inner side, and the housing locking the electric wire holding member at an end portion in a connector insertion direction;
a tubular shield shell in which a part of the electric wire including the terminal is accommodated on an inner side, a part of the shield shell on the connector insertion direction side is embedded in the housing, and a part of the electric wire holding member is accommodated on the inner side in a connector extraction direction opposite to the connector insertion direction;
a tubular braided body in which a part of the electric wire including the terminal is accommodated on an inner side and which is electrically connected to the shield shell;
a shield ring fixed to a connecting part, in which the shield shell and the braided body are connected to each other, from an outer circumferential side in a diameter reduction direction; and
a water blocking member which prevents entry of water to the inner side of the housing and the shield shell, wherein
the electric wire holding member includes:
a main body disposed at a position facing the inner circumferential surface of the end portion of the shield shell in the connector extraction direction, and
a protrusion formed to protrude from the main body along the electric wire in the connector extraction direction between the electric wire and the braided body,
the braided body is disposed to cover the outer circumferential surface of the protrusion, such that the end portion of the braided body in the connector insertion direction reaches the connecting part, and
the water blocking member is wrapped around the braided body in a spiral shape to cover at least from the end portion of the protrusion in the connector extraction direction to the connecting part.
2. The water stop structure of the shield connector according to claim 1 , wherein
the electric wire holding member further has an inclined surface which is inclined to extend from the end portion of the protrusion in the connector extraction direction toward the connector insertion direction, as the outer circumferential surface of the protrusion.
3. The water stop structure of the shield connector according to claim 2 , wherein
the electric wire holding member is formed such that the end portion of the main body in the connector extraction direction is located on diameter reduction side than the end portion of the inclined surface in the connector insertion direction, and
the shield ring is disposed on the connector insertion direction side than the end portion of the inclined surface in the connector insertion direction.
